Notes:
Based on the solidification features of ductile iron and affectingfactors for ductile iron shrinkage defect, the model of the ductile iron solidification isbuilt and put forward a new defect predictive method EIECAM (Enclosed-Isolatedarea Expansion and Contraction Accumulation Method) model to predict defect. inDECAM, the liquid shrinkage, solidified shrinkage and graphitizing expansion duringsolidification are computed dynamically in the enclosed-isolated area , and the effectof graphite expansion on the wall movement is also accounted. Based on this methodend cover of QT500 ductile iron casting is simulated and made the defect predictive,study its solidification process and the defect generation position, and make theexperimental identification on the defect. It is resulted that the method can be able topredict the casting defect authentically
